This transcript is based on a tape-recorded interview deposited at the Center for History of Physics of the American Institute of Physics. The AIP's interviews have generally been transcribed from tape, edited by the interviewer for clarity, and then further edited by the interviewee. If this interview is important to you, you should consult earlier versions of the transcript or listen to the original tape. For many interviews, the AIP retains substantial files with further information about the interviewee and the interview itself. Please contact us for information about accessing these materials.

Please bear in mind that: 1) This material is a transcript of the spoken word rather than a literary product; 2) An interview must be read with the awareness that different people's memories about an event will often differ, and that memories can change with time for many reasons including subsequent experiences, interactions with others, and one's feelings about an event. Disclaimer: This transcript was scanned from a typescript, introducing occasional spelling errors. The original typescript is available.

Interview with Dale Van Harlingen, Professor of Physics at the University of Illinois, Urbana-Champaign. He recounts his childhood in Ohio and his undergraduate education at OSU in physics and his early work on SQUIDS. Van Harlingen discusses his mentor Jim Garland, and he explains his decision to stay at OSU for graduate school to develop SQUID devices to make phase-sensitive measurements. He explains the opportunities that gained him a postdoctoral appointment at the Cavendish Laboratory in Cambridge where he developed his expertise in the Josephson Effect, and where he met John Clarke, who offered him a subsequent postdoctoral position at UC Berkeley. Van Harlingen describes his foray using SQUIDS to push the quantum limit, and he explains his decision to join the faculty at Illinois, where he was impressed both with the quality of the research and how nice everyone was. He describes joining the Materials Research Laboratory and the development of the Micro and Nanotechnology Laboratory, and he conveys his admiration for Tony Leggett. Van Harlingen discusses his research in NMR microscopy, grain boundary junctions, scanning tunneling microscopy, vortex configurations, and he describes his current interest in unconventional superconductors. At the end of the interview, Van Harlingen conveys his excitement about the national quantum initiative as a major collaboration between universities and National Labs, and he explains his motivation to understand if Majorana fermions actually exist.
